Originally, Rolex Oyster Perpetual GMT-Master timepiece which became the official timepiece of the Pan Am pilots, and was designed so as to facilitate flight between different time zones as the age of intercontinental flight reached its boom. To avoid any confusion, Rolex replica equipped its timepiece an additional GMT hand and a dual colored bezel which would clearly show whether it is night or day in that time zone. Except being very readable in that manner, the new color scheme with the bezel being divided into red and blue halves looked pretty neat and became very sought after. In those days, the best way to create a bi-colored bezel included a transparent Plexiglas section which revealed painted surfaces underneath it.
A new chapter began about nine years ago when Rolex began using Cermachrom inserts on its rotatable bezels. The obvious advantages of ceramic as a material are its glossy appearance and more importantly its extreme resilience, simply because it does not corrode, it is not affected with ultra-violet light and is virtually scratch proofed. Nevertheless, the initial complex process allowed the creation of this type of bezel solely in black color. The following breakthroughs were the addition of green and blue colors to the list of options, together with the creation of the first two-toned insert (in black and blue) that was featured on the previous Oyster Perpetual GMT Master II piece which saw the light of day last year.
Some five years after the creation of the first model, the brand mastered a new technique which allowed it to make a dual colored bezel of anodized aluminum. New color schemes followed one of the examples of the new color arrangement that was seen on the first Oyster Perpetual GMT-Master II watch from 1982. The second generation of the watch abandoned a fixed GMT hand and offered the wearer an option to set it to time zone of its preference. This way, the pilot’s timekeeper got the third time zone which could be read in the combination with the movable bezel. Despite the addition of new colors, the original red and blue scheme still remained a crowd favorite and the best liked when compared to all of the following iterations.
Still, the original iconic colors were impossible to create up to this day. This was due to the process of creation of ceramic parts itself. During the manufacturing of Cerachrom bezels, mineral pigments are added to the mixture to add the color. These minerals are utilized because they can be exposed to extreme temperatures which are necessary in order to create compact and resistant final products. Since there are no red minerals in nature, it is clear why the “Pepsi” color scheme still remained an impossible feat. The difficulty only proved to be a challenge to the rolex replica which developed a secret process that allowed coloring to red. Even this was not adequate since the other part of the bezel needs to be in blue color. The final hurdle was passed with the development of the solution which is used to treat a half of the bezel during its creation so it would turn blue.
The remarkable bezel that can be turned both ways in order to show the time in the third time zone is matched with a black laquer dial as it was originally the case. This black face includes hands and applied hour markers made of 18 K gold and coated with highly luminous Chromalight material.

In 1957, after originally launching it, the iconic Omega Speedmaster celebrates its 60th anniversary. No later than a decade, it seems be known as the “moonwatch” gradually. All timepiece fans learn that the Speedmaster by Swiss Omega replica was chosen by American NASA to be the official timepiece worn by Apollo mission astronauts and eventually to the moon – some times.
The once racing- and pilot-themed Speedmaster became the timepiece synonymous with the moon and everything in accordance with the astronauts since the moon missions. It is a persona that keeps on enduring today, even though Omega has yet to determine how it will truly be a part of contemporary spaceflight activities so as to secure future relevance in this topic. What has really helped the Speedmaster endure, however, isn’t just a connection to the historic moon missions or NASA, but rather its winning layout. What’s more, the Speedmaster has been rendered in so many ways with so many variants that even highly trained specialists have trouble keeping track of all the models.
The steel versions of the replica watches have a printed life-like representation of the moon in the discs, while the gold and platinum versions have textured moonphase discs which offer a different appearance. The platinum version of the watch even goes so far as to have a small magnifier disc where the date pointer hand is. This is pretty cool, but I recall Omega saying that the part was such a pain to make that they would not have been able to make it for a non-limited edition.

There are many things related with the sandwich-style construction of the case, as well as the fact that the various parts comes with different widths. In spite of the size, the case is very comfortable as a whole and attractive /amazing on the wrist, and its details do merit close inspection. The case is water-proof to 100 meters and has a sapphire crystal on both ends, with a display case back providing with a view of the wise in-house-made movement.
